SimScalator — April’s Winner: Particle Analysis in Hourglass

Particle Analysis with SimScale

Every month we gather here at SimScale to see what simulations our colleagues have submitted for the SimScalator challenge.

This contest is not only an opportunity to be creative and perform interesting simulations, but it is, first and foremost, one of our ways to discover possible improvements to the SimScale platform.

After Kristina won the SimScalator in March, this month our colleagues Ahmed, David, and Sebastian raced for the cup. Let’s take a look at their projects and discover the winner.

Propeller of 3D Printed Ducted Fan — CFD Analysis

It has become a tradition for David to participate in the competition and we always look forward to seeing what new simulation he brings. This time it was a CFD analysis. He simulated the propeller of a 3D printed ducted fan quadcopter.

This project is public, so it is possible to just copy it and use the setup as a template for your own simulation.

Thermal-Structural Analysis of a Space Glider

It didn’t take long for Johannes to readapt to life at SimScale. In the same week he came back from his student exchange in Copenhagen, he started working on his SimScalator project.

He simulated a space glider, examining the thermal and mechanical loads on its way to space—more precisely from a sea-level position to a height of 100 km.

During its journey, the space glider crosses different zones with different temperatures. Also, the pressure (important for the structural analysis) and the density (needed for the calculation of the convection coefficient) depend on the altitude. Both were approximated with the formula from the Engineering ToolBox.

The speed and the position of the aircraft were expressed by time and with the CAD model from GrabCAD member Thomas Frevillier, the simulation was carried out. With the results, the structural and thermal loads from the pressure and temperature field can be determined, but for a complete analysis, it is also necessary to consider the aerodynamic forces acting on the glider.

Harrier Jump Jet — CFD Analysis

The Harrier, informally referred to as the Harrier Jump Jet, is a family of jet fighters that can take off and land vertically. In this project, Ahmed simulated the vertical lift-off and landing of a Harrier in order to visualize the flow when it is thrusting to take off or land.

Particle Analysis in Hourglass — The Winner

Performing his first simulation on SimScale, Sebastian took the challenge very seriously. He learned how to use the platform and chose one of the most complicated analysis types: particle simulation.

hourglass Particle Analysis

Once in the SimScale workbench, Sebastian performed the particle analysis of his hourglass, and the results showed the linear velocity of the particles, depicted on a logarithmic scale.

Below is a video of the simulation. Creating a smooth movement of the hourglass geometry caused him a bit of a headache, but the final result was a delight for the audience:

As he familiarized himself with SimScale, he was able to propose many suggestions on how to improve our users’ experience which, along with his simulation, brought Sebastian the SimScalator cup.
